ABSTRACT:
A method and/or apparatus for drying material is provided, the method comprising the steps of disposing the material in a heating unit to have the heating unit heat at least part of the liquid particles of the material, disposing a charged electrode unit so as to be adjacent one side of the material when the material is disposed in the heating unit and to define a plurality of electrostatic fields that are serially arranged in substantially a like repeating pattern and that are substantially constant and non-oscillating so that the fields at least partially extend through the material while the material is disposed in the heating unit, moving the material in one direction through the heating unit to cause at least a portion of the material to have the particles of liquid thereof serially moved through the electrostatic fields while the portion of the material is being heated by the heating unit whereby the electrostatic fields augment the drying effect of the heating unit on the material, and disposing a member between each pair of adjacent electrostatic fields to change the normal shape of the adjacent electrostatic fields between the electrode unit and the material so that when the material is moved in the one direction, the particles of liquid of the portion serially move through the thus reshaped electrostatic fields while the portion of the material is being heated by the heating unit.
